can't do addBug via probes in heatbugs anymore?

[Rick Riolo]

Am I right that one can't do the nice little demo
of adding a new heatbug to the heatbugs demo by
a) probe a bug,
b) use mb3 to bring up a probe of that bug with up-class button
c) click up-class to the top object (with copy method)
d) click that copy method to make a copy.
e) drag and drop that copy into the addBug method parameter slot
f) click addBug
(this is from manor's little "probe demo" note of
some time back.

Now if I click that copy in the top level object 
I get a core dump after this message:

badger-rlr)*** event raised for error: BlockedObjectAlloc
*** function: _i_Object_s__copy(), file: DefObject.m, line: 487
> Requested operation is defined by the Object superclass of the GNU

*** execution terminating due to error

I guess to be able to do this, one would need
to define a custom copyBug method (which does the createBegin/end) 
method in HeatbugObserverSwarm, say, and put a probe to 
that copy method in the observer probe.

Am I right about all this?

If so, you might want to fix the heatbugs demo
and also put together an update of manor's little
probe notes.
